Colby McHenry 57e0854213 fix(explore): recognize Wrangler-style "generated by … by running" banners (CG-25) ...

Cloudflare Wrangler's `worker-configuration.d.ts` (~12k lines of ambient
types) carried no banner any GENERATED_CONTENT_PATTERNS entry matched:
every existing marker requires `DO NOT EDIT`, a standalone `@generated`,
`<auto-generated>`, or the literal `automatically/auto-generated by`
phrasings. Wrangler emits a bare `Generated by Wrangler by running
`wrangler types``, so the file ranked with pen 1.00 and won 79.4% of an
explore envelope on generic token overlap alone (CG-24).

The discriminator is the reproduction instruction, not the word
"generated": the banner must name a tool AND then say `by running`, i.e.
two separate "by" clauses. That keeps prose out — "the nightly summary is
generated by running the ETL job" has only one — while catching every
CLI-driven emitter that tells you how to regenerate.

Precision swept over 441,856 files across the whole local source tree: 5
hits, all genuine Wrangler output, no false positives.

Isolated before/after on the CG-24 repro (same query, same index, only
the `files.generated` flag differing):

  before  pen 1.00  score 115.0  share 79.4%  3 files rendered
  after   pen 0.30  score  35.4  share 21.1%  4 files rendered

The new pattern stays in the existing table position, below the header
window the detector scans, so the module still does not classify itself.
